These two prices are not directly comparable

Klinic: the $99 figure is a per-visit consultation fee, not a month of treatment - the medication is billed separately.

Medications

NAD+sermorelinglutathioneMIC + B12GHK-Cu

Pros

✓Prices are published openly for every product, with the renewal rate shown alongside the introductory one: NAD+ $89 first month then $149, sermorelin $109 then $219, glutathione $79 then $149, oral sermorelin $79 then $159, MIC + B12 $89/mo and GHK-Cu cream $109/mo (checked July 28, 2026)
✓Three delivery formats for NAD+ - injection, nasal spray and liposomal liquid - so needle-free options exist
✓Products are described as American made and third-party tested
✓The intake is short and a licensed provider reviews it before anything ships, with free 2-day shipping
✓No insurance required and no membership fee stacked on top of the product price

Cons

✗This is not a GLP-1 weight loss service. System Labs sells no semaglutide, no tirzepatide and no GLP-1 of any kind - the words do not appear anywhere on its site. If you are shopping for weight loss medication, this provider cannot supply it
✗We could not find any statement that the compounded peptides are not FDA-approved. That disclosure is standard across this category and its absence is the single biggest gap on the site
✗There is no refund or cancellation policy published at all - only a privacy policy and terms page
✗No independent review signal exists: no Trustpilot profile, no BBB file, and no rating displayed on site
✗Introductory pricing roughly doubles at renewal on most products, and the renewal price is the one you will pay for the rest of the course
✗Sermorelin, GHK-Cu and high-dose NAD+ have limited published human trial evidence for the benefits implied - 'perform 10 years younger' style claims are not supported by the kind of trials that back GLP-1 medications
✗No published phone number, support hours or physical address
✗The 'up to 1600mg' NAD+ potency claim is presented as an advantage without any evidence that higher doses produce better outcomes

Medications

semaglutidetirzepatideoral semaglutideorforglipron

Pros

✓Insurance-first, and it does the paperwork: Klinic states it handles the prior-authorisation process with your insurer on your behalf, which is the single biggest barrier to covered GLP-1 access
✓Transparent visit pricing - $99 initial visit and $75 follow-up visits
✓Prescribes FDA-approved branded medication including Zepbound, Wegovy, oral Wegovy and Foundayo
✓Accepts hundreds of insurance plans including Medicare and Medicaid, which almost no telehealth weight-loss service does
✓Nationwide network of licensed, board-certified independent providers
✓The whole intake and matching process is quoted at about 15 minutes, with insurance verified before you are matched
✓Support published as available 24/7/365 at support@klinic.com
✓Covers addiction, depression and chronic disease alongside obesity, so patients with overlapping conditions are not sent elsewhere

Cons

✗Klinic is a matching platform, not the practice - you are connected to "Independent Practitioners", so consistency depends on who you draw
✗The marketing is confusing about compounding. One landing page sells "oral compounded semaglutide" with ondansetron added for nausea, while the FAQ on that same page says Klinic prescribes the FDA-approved branded version only, and the main weight-loss page says all medications prescribed are FDA-approved branded ones
✗Visit fees are per appointment, so the real annual cost depends on how often your provider wants to see you
✗Medication cost is entirely separate and depends on your insurance - a covered GLP-1 can be $25/month, an uncovered one over $1,000
✗Prior-authorisation support is not a guarantee of approval, and the site does not publish approval rates
✗No phone number is published
✗Typos and inconsistencies in the on-site copy ("Tirzepttide", "Fill our a short form") do not inspire confidence in the detail work
